CONTROLLING VALVE FOR HYDRAU LIC OIL STORAGE AND DISTRIBUTION SYSTEMS.

Application filed February To all whom it may concern:

Be it known that I, FRnoEmoK G. FARR, a citizen of the United States ofAmerica, residin at New York city, in the countyof New 01k and State ofNew York, have invented certain new and useful Improvements inControlling Valves for Hydraulic Oil Storage and Distribution Systems,of which the following is a specification, reference being had thereinto the accompanying drawings.

The invention relates to hydraulic oil storage and delivery systems andhas particular reference to the construction of the controlling valve,being an improvement upon my former Patent No. 1,286,971, dated December10, 1918. It is the particular object of the present improvement toavoid the drainage of the displacement liquid from laterally-extendingportions of the conduit therefor, thereby avoiding the necessity ofrefilling such portions when delivery of oil is made. To this end theinvention consists in the construction as hereformer patent inafter setforth.

In the drawings:

Figure 2 is a section in a plane at right angles to Fi re ,1.

is the va ve casing which at one end is connected to the supply conduitB for the water under pressure and at its opposite end is connected tothe drain conduit D is acentral chamber within the valve casing which isseparated from end chambers E and F respectively connecting to theconduits l5 and C by ported partitions G and H. l and J are valvespreferably of the pocket type for controlling the ports in thepartitions G and H and these valves are mounted on a common stem K bywhich when one valve is seated the other valve is withdrawn from itsseat. L is an operating lever which engages a yoke M on the valve J foractuating the same, said lever being fulcrumed at and passing out fromthe chamber F through a slot 0 in the wall thereof. The construction asthus far described is essentially the same as that of my above referredto.

When the valve is connected into a hydraulic delivery system, thechamber D is connected with the conduit which extends to the bottom ofthe storage tank and through which water is delivered for the G. throughthe conduit 9, 1922. Serial no. 535,422.

displacement of oil. Thus, whenever the lever L is raised to seat the,valve J and unseat the valve 1, water under pressure from the conduit Bis delivered into the chamber D and through the connected conduit suchas P extending to the storage tank. On the other hand, when the lever Lis lowered, seating the valve 1 andunseating the valve J, the water ispermitted to drain from the chamber D into the chamber F and drainconduit C. It frequently happens in tire installation of such apparatusthat the conduit 1 must extend laterally for a considerable distance tothe bottom of the tank. ere this is the case with the construction ofvalve shown in my former patent, there is nothing to prevent thedraining out of all of the Water in the lateral portion of the pipe P,so that when the lever is reversed, it is necessary to refill this pipebefore edecting displacement of oil from the storage tank. With myimproved construction such defect is avoided by locating the portedpartition H, through which communication is established, between thechambers D and F above the level of the conduit P. This will form a trapwhich will hold all of the water in the lateral portion of said conduitand will permit the drainage of Water which is above the level of thepartition. Therefore, whenever the valve 1 is opened, there will be apractically instantanfious delivery of water efilgecting a correspondingdisplacement of 01 In order to obtain the desired relative location ofthe partition H andthe conduit P, the latter is coupled to a portion Q,the casing which extends downward at one side of the chamber F. Thisprovides full area for the passage of the liquid and at thesame timelocating the conduit 1? below thartition H, as above described.

' at I claim as my invention is:

1. A valve comprising a casin formed of a single piece of materialhaving parallel alinement ported partitions divlding the same into inletand outlet chambers and an intermediate chamber, a delivery connectionbefore extending downward m into the storage tank, on

to said intermediate chamber arranged below the level of the partitionseparating the same from said outlet chamber, and valves foralternatively closing the ports of said partitions.

2. A valve comprising a casing divided llltl by ported partitionsinto aninlet chamber in its upper portion, an outlet chamber in its lowerportion and an intermediate chamber, valves controlling the ports insaid partitions,

alternatively seating the same, and a delivery connection for saidintermediate chamber means within said valve casing for trapping theliquid in said delivery conduit from draining into said outlet.

t 4. A valve comprising a casing divided by so arated orted partitionsinto an upper inl et cham er, a lower outlet chamber and an intermediatechamber for connection with a delivery conduit, valves having a commonstem for controlling said ported partitions and alternatively seatedthereon, and an extension of said intermediate chamber down- I wardbelow the partition between the same and the outlet chamber to whichsaid deliva common valve'stem for said valves bersand an intermediatechamber, a delivr ery connection to said intermediate chamber arrangedbelow the level of the partition separating the same from said outletchamber, valves for alternately closing the ports of said partitions,and a common valve stem for said valves.

6. A valve casing formed'of a single piece' of material havinghorizontally disposed ported partitions dividing the same into inlet andoutlet chambers and an intermediate chamber, a delivery connection tosaid intermediate (hamber below the level of the partition separatingthe same from said outlet chamber, valves for alternately closing theports of said partitions, a common valve stem for said valves, and meansmounted within said outlet chamber for actuating said valve stem.

In testimony whereof I aflix my signature.
